Audio Front-End

6.1 Main MIC, Receiver, Headset and OPamp stage.

The audio front-end essentially consists of voice and audio data paths. Figure 28 shows the block diagram of the audio front-

end. All voice band data paths comply with the GSM 03.50 specification. Mono hands-free audio or external FM radio

playback paths are also provided. The audio stereo path facilitates CD-quality playback, external FM radio, and voice

playback through a headset.

Figure 28. Audio Front-End Block Diagram

Figure 29

shows the digital circuits block diagram of the audio front-end. The APB register block is an APB peripheral that

stores settings from the MCU. The DSP audio port block interfaces with the DSP for control and data communications. The

digital filter block performs filter operations for voice band and audio band signal processing.

The Digital audio interface (DAI) block communicates with the system simulator for FTA or external Bluetooth modules.
